Are Any Changes in Carotid Intima–Media Thickness Associated with Cardiometabolic Risk Among Adult Bantu Central African Hypertensive Patients from Monkole and Biamba Marie Mutombo Hospitals? Vasc Health Risk Manag 2022; 18:453-461. [PMID: 35800291 PMCID: PMC9255902 DOI: 10.2147/vhrm.s366339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 06/13/2022] [Indexed: 11/23/2022] Open
Abstract
Background Several classic/traditional risk factors are associated with intima–media thickness (IMT), a novel risk of cardio metabolic risk (CMR) in the literature but not in Kinshasa, a megacity prone to CMR. Thus, the objective of this study was to evaluate potential correlations between inflammation, kidney function, psychological stress, hemodynamics, and changes in IMT. Methods This cross-sectional study was carried out between 2018 and 2021 within Monkole and Biamba Marie Mutombo Hospitals, respectively, and randomly selected from 10 health structures from East and West of Kinshasa, Capital of Democratic Republic Congo (DRC). A random sample of adult hypertensive Bantu Central Africans was examined after bivariate correlations and multiple linear regression. Results Out of 280 patients with 140 men and 140 women aged 62 ± 11 years, the mean carotid intima–media thickness (CIMT) was 1.06 ± 0.5 mm and 73% (n = 204) patients had uncontrolled hypertension. After controlling for confounders, 52.9% variations (R2) of CIMT were independently and significantly (P = 0.037) predicted by CRP, 24-hour proteinuria, urinary albumin/creatinine ratio, duration of hypertension, heart rate, hip circumference, and psychological stress with Equation Y = 0.717 + 0.87 × CRP + 0.02 × 24 H – proteinuria + 0.005 × urinary albumin/creatinine ratio + 0.05 × duration of hypertension + 0.001 × heart rate + 0.006 × hip circumference + 0.017 × psychological stress. Conclusion There is an urgent need to control inflammation, impaired renal function, cardiac rhythm, peripheral obesity, longer duration of hypertension management, and stress, which are emerging as specific novel determinants of the subclinical atherosclerosis for those Bantu Central African hypertensive patients.

Arch Med Sci Atheroscler Dis 2020; 5:e245-e254. [PMID: 33305063 PMCID: PMC7717441 DOI: 10.5114/amsad.2020.98945] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Accepted: 08/15/2020] [Indexed: 02/02/2023] Open
Abstract
INTRODUCTION The atherosclerosis process is highly accelerated in patients with chronic kidney disease (CKD). Oxidative stress is considered as one of the pro-atherogenic factors involved in accelerating the atherosclerosis process of the carotid artery. The aim of the present study was to determine the relationship between oxidative stress markers and the progression of carotid atherosclerosis in CKD patients. MATERIAL AND METHODS The study was conducted on 162 patients with CKD and 40 controls, and the disease stage was scored between 2 and 5D. Blood samples were taken and advanced oxidative protein product, myeloperoxidases, malondialdehyde, nitric oxide, glutathione, and oxidised low-density lipoprotein were measured. Furthermore, we studied the correlations between these biomarkers and clinical and para-clinical cardiovascular complications. RESULTS The average age of patients was 56.5 years. The oxidative stress markers average ± SD levels in CKD groups compared to the control were as follows: advanced oxidation protein product (61.89 ±1.4 vs. 26.65 ±1.05 µmol/l), myeloperoxidase (59.89 ±1.98 vs. 38.45 ±1.98 UI/ml), malondialdehyde (6.1 ±0.12 vs. 3.26 ±0.03 µmol/l), nitric oxide (65.82 ±1.06 vs. 52.19 ±2.1 µmol/l), glutathione (52.21 ±1.3 vs. 89.4 ±2.6 IU/ml), and oxLDL (15.57 ±1.07 vs. 1.72 ±0.82 µmol/l). While the glutathione level decreased significantly in advanced CKD stage (p < 0.05), the concentrations of all the other biomarkers increased significantly in accordance with CKD score (p < 0.05). CONCLUSIONS Cardiovascular diseases, mainly atherosclerosis, can be diagnosed indirectly by measuring oxidative stress markers. Furthermore, theses markers can be used to predict the progression of CKD, for better management of the disease.

Abstract
OBJECTIVES To evaluate the prevalence and determinants of increased carotid intima-media thickness (IMT) in a population of black hypertensive patients and it influence of on the assessment of their overall cardiovascular risk. PATIENTS AND METHODS This was a 16-month, cross-sectional study conducted in the outpatient unit of the cardiology department of the Campus teaching hospital of Lome, and included 1203 hypertensive patients, both sexes, aged 35 years and more. Each patient benefited from a carotid IMT measure. Carotid IMT was increased if it was>0.9mm and the plaque was defined as a carotid IMT>1.2mm. RESULTS The mean age of our patients was 53.3±10.4 years with a sex ratio of 1.6 in favor of women. The duration of hypertension was less than 5 years in 56.7% and hypertension was grade 1 in 47.7% of cases. The mean carotid IMT was 0.89mm±0.20. The prevalence of the increased carotid IMT was 45.8% and that of an atheroma plaque was 15.8%. Carotid IMT was correlated with age (P˂0.0001), duration of arterial hypertension (P=0.01), history of stroke (P˂0.0001), and presence of left ventricular hypertrophy to cardiac ultrasound (P=0.01). The overall cardiovascular risk was modified after taking into account the carotid IMT. An increase in cardiovascular risk was observed in 30.5% of hypertensive patients. CONCLUSION Increased carotid intima-media thickness is frequent in Togolese hypertension. The determining factors are age, duration of arterial hypertension, left ventricular hypertrophy and stroke. The systematic measurement of the carotid intima-media thickness would better evaluate the overall cardiovascular risk for our patients.

Effect of metabolic control on oxidative stress, subclinical atherosclerosis and peripheral artery disease in diabetic patients. J Diabetes Metab Disord 2015; 14:84.

Abstract
Introduction By rising diabetes mellitus prevalence, the prevalence of its most complication; cardiovascular disease (CVD) is also increasing. Moreover, oxidative stress has important role in pathogenesis of diabetes and its complications. We investigated relationship between total antioxidant status (TAS) and surrogate measures of subclinical atherosclerosis (SA) with glycemic status in diabetics. Methods & materials In a cross-sectional study, we recorded height, weight, waist circumference (WC) and blood pressure of 267 subjects. Blood samples were collected to measure fasting blood sugar (FBS), glycated hemoglobin (HbA1c), lipid profiles and TAS. The surrogate measures of SA were Carotid Intima Media Thickness (CIMT), and Ankle Brachial Index (ABI). Results We found significantly lower TAS leves and ABI values and higher CIMT in diabetic patients especially in poor glycemic group. There was a nonsignificant, weak correlation between TAS, ABI and CIMT with glycemic status (r = −0.10, −0.16, and +0.09, respectively). Multivariate regression analysis showed a significant influence of increasing age and diabetes duration on worsening CIMT in poor glycemic group. Conclusions Our study showed poor glycemic control leads to worse CIMT by increasing age and duration of diabetes. However we did not find a significan correlation between glycemic status and TAS levels. We suggest CIMT measurement along with other SA markers in poor glycemic diabetics, especially in older patients with longer duration of diabetes, to identify high risk CVD patients.
